Inrush Current Limiters (ICL) Procurement Notes

Verify that the specific PTCEL13EL variant matches the required 120 Ohm nominal resistance and ±30% tolerance for the target application. Confirm that the 85 mA current rating and 440 VAC / 625 VDC voltage limits exceed the operational stress parameters. Ensure the radial lead pitch and body dimensions fit the designated PCB footprint. Check RoHS compliance status against project environmental regulations before finalizing procurement orders.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a radial PTC thermistor is required for inrush current suppression or overcurrent protection. The 120 Ohm initial resistance and 85 mA holding current define the baseline performance characteristics. Consider the -40°C to +105°C operating range to ensure functionality within the expected environmental conditions. Verify compatibility with standard PCB assembly processes due to the radial lead configuration and bulk packaging format.
